3 1. Introduction eries FMAX is an absolute magnetic length measuring system and only of use for recordation of lengths. It consists of a guide carriage, where sensor technology and translator are placed, and a guide rail FMAB. A magnetic tape is installed on the guide rail. The guide carriage is contactless slided over the magnetic tape. For interface a R422 is available. Further interfaces are in preparation. The absolute measuring system offers crucial advantages: no reference adjustment necessary direct measurement measuring lengths up to 650 mm high resolution up to 0,01 mm repeating accuracy +/- 0,01 mm protection against dirt and dust easy installation Typical applications are paper cutting machines, hydraulic presses, wood- and sheet metal processing machines. 2. afety Attention! To ensure a perfect function of the FMAX-ystem the following installation guidelines must be strictly observed and followed. Otherwise the guarantee expires and ELGO Electric GmbH takes no liability and guarantee for malfunctions or damages caused e.g. by incorrect installed wires or other external sources of error or interference, which are exactly explained below. Please read the instructions carefully before putting the controller into operation.. As well ELGO Electric GmbH is not liable for possible machine- and/or personal damages, which could arise through defective material on the measuring system and the following circuit. The machine producer is obliged to take and to carry out appropriate security relevant measures. The type label, which can be found on the measuring system is of use for the precise identification of the measuring system. It gives information regarding the precise type designation (see chapter 10. type designation on page 8), delivery date and production number. These details are always necessary, when contacting ELGO Electric GmbH. 2.1 Fault clearance Place of Installation At least 0,5 m away from inductive and capacitive disturbance sources like contactor, relays, motors, switching power supply, clocked controller, etc. In principle lay the FMAX-cable separated from power wires and keep distance to disturbance sources. For installation near other magnets, a minimum distance to the magnetic tape of 100 mm is necessary. If there occurs interferences in spite of applying all above mentioned measures proceed as follows: 1. Add RC elements over contactor reels of AC contactors (for example 0,1 μf/100 Ω). 2. Add recovery diodes over DC inductances 3. Add RC elements over each engine phase (in connector box of the engine) 4. Install a power filter before the external power supply 3

The following illustration shows the three magnetic tracks with following north- and south pole magnetization, sensed by magneto-resistive resistor measuring bridges. Between the single magnetic tracks there always is an equal shifting ΔX. This is evaluated together with the single signs of the resistive resistor measuring bridges and delivers an absolute value. An unambiguous classification of a absolute position is possible by the combination of the phasing of the three magnetic tracks. The phase position zero repeats every 650 mm for each of the three tracks. Illustration 1. functional principle FMAX

6 6. Installation/first start up 6.1 Place of Installation At least 0,5 m away from inductive and capacitive disturbance sources like contactor, relays, motors, switching power supply, clocked controller, etc. In principle lay the FMAX-cable separated from Power wires and keep distance to disturbance sources. For installation near other magnets, a minimum distance to the magnetic tape of 100 mm is necessary. 6.2 Installation of the guide carriage Take four M4-screws to fasten the guide carriage. 6.3 Guide rail The guide rail contains a magnetic tape and a profile rail. Factory made the magnetic tape is stick together with the profile rail Installation of the rail Take four M4-screws to fasten the guide rail. For that, there are drill hole at the ends. Attention: For installation of guide carriage and guide rail pay attention to the markings on the magnetic tape and on the sensor. A wrong installation will not deliver correct values. 7.

Interface The measuring system FMAX is provided with an interface in format R422. The data transfer has the following format: 9600 Baud 1 tart Bit 8 Daten Bits 1 top Bit o Parity Data record: The actual value will be transferred every 2 msec. with following data record: 02h TX AB-Datas 03h AB-Datas AB-Datas AB-Datas AB-Datas AB-Datas ETX BCC The Block check sum is an exclusive OR of all datas inclusive TX and ETX. All values will be transferred in ADCII-format. 6

7 8.1 Teaching procedure / Offset hould the desired display value differ from the factory-made adjusted original offset, a settlement can be carried out by the external counting unit. Alternatively the offset can be changed by the R-422 interface of the FMAX (see point 8.11 and 8.12) Teaching procedure: Indication: On delivery guide carriage and guide rail are numbered and belong together in pairs. A teaching procedure is necessary, if only the guide rail or the guide carriage has to be replaced. A teaching procedure has to be carried out as follows: 1. Guide carriage and guide rail are installed and the measuring system can stand at any place. 2. Afterwards the following record has to be sent to the measuring system: 02h TX 4ch L = teaching procedure is started 03h ETX 4dh M = BCC 3. The guide carriage has to be moved 30 mm in one direction with a speed of 0,01 m/s max. (10 mm/sec. max.) and following back again. 4. Afterwards the following record has to be sent to the measuring system: 02h TX 42h B = teaching procedure is finished 03h ETX 43h C = BCC The teaching procedure is completed Offset adjustment After installation and connection of guide carriage and guide rail a value will be transferred over the interface. As this value does not agree with the machine offset, an offset can be deposited usually at the controller side or directly at the measuring system. In order to adjust this offset at the measuring system, the ensor has to be moved to the machine offset. Afterwards the following record has to be sent: 02h TX 4eh = adjust zero point 03h ETX 4fh O = BCC The measuring system is adjusted to offset. All transmitted values are now related from this offset. Attention: This offset adjustment needs to be carried out at any change of guide carriage or guide rail. In case the counting direction cannot be changed in the controller, the complete slide-system has to be turned over. 7
